Safe environment-friendly reducer for firework

Abstract

The invention provides a safety reducing agent of an environment-friendly firework, wherein the constituents include 20 to 73 parts of natural coal slack; 20 to 50 parts of natural pyrite ores; 2 to 5 parts of natural perlite powder and 5 to 25 parts of charcoal by weight. The invention replaces the sulphur as a reducing agent, so fireworks and crackers have the greatly reduced sulfur dioxide pollution to the environment when being set off; The compositions of the invention are chiefly crystals, and have the conducting property and will not produce the static electricity easily, thereby solving the static electricity problem fundamentally; and the invention contains fiber substances having pores and has unique functions of thermal insulation, heat preservation and abrasion resistance, thereby increasing the burning rate, enhancing the burst effect, being favorable for improving the cost performance and ensuring the safety of production and warehousing and transportation. The main materials of the invention have high melting points and are not easy to catch fire, thus greatly increasing the safety coefficient and providing the good economic benefit.

Description

Technical field: [0001] The invention relates to a reducing agent for firecrackers and fireworks. Background technique: [0002] Traditional fireworks drugs are composed of two major components: oxidizing agents (potassium nitrate, potassium chlorate, potassium perchlorate, etc.) and reducing agents (sulfur, charcoal, silver powder, etc.). Sulfur has the disadvantages of easy to generate static electricity, low melting point, flammable, explosive, easy to oxidize, and easy to generate sulfuric acid and sulfurous acid after being damp, causing acid rot. It is a high-risk and high-pollution product. And when it burns, it reacts violently and emits a large amount of sulfur dioxide, which seriously pollutes the atmosphere. [0003] If pyrite (sulphur fine sand) is used, "Sanhe Powder" mixed with flammable aluminum powder, expanded perlite powder, and stabilizer and desensitizing agent is not only expensive, but also has a single purpose and can only be used as firecrackers. . ...

AI Technical Summary

Problems solved by technology

Sulfur has the disadvantages of easy to generate static electricity, low melting point, flammable, explosive, easy to oxidize, and easy to generate sulfuric acid and sulfurous acid after being damp, causing acid rot. It is a high-risk and high-pollution product.

And when it burns, it reacts violently and emits a large amount of sulfur dioxide, which seriously pollutes the atmosphere.

[0003] If pyrite (sulphur fine sand) is used, "Sanhe Powder" mixed with flammable aluminum powder, expanded perlite powder, and stabilizer and desensitizing agent is not only expensive, but also has a single purpose and can only be used as firecrackers.

Use sulfur sand, sulfur, barium nitrate, and silver powder to make explosives, which are also expensive and can only be used as firecrackers, and storage and transportation are extremely unsafe
